Mesh loading problem

Hello.
Im loading mesh with this script

  BABYLON.SceneLoader.Append("./assets/", "Low_Note8.gltf", scene, function (scene) {
            });

and it gives me this error.


any ideas why it happens? All the forums i read didnt helped me Thanks

Have you imported the babylonjs-loaders library?
You can find more information in Load from any file type - glTF, OBJ, STL, etc. - Babylon.js Documentation

Yeah, I imported this one
https://preview.babylonjs.com/loaders/babylonjs.loaders.min.js
Though ill read again the article and try it out more

Can you try to drag and drop you gtlf file and all its data to sandbox.babylonjs.com?

I had an issue with the loader at preview.babylonjs.com
It reversed the normals of my model. When I used the loader from:
https://cdn.babylonjs.com/loaders/ xxx

It worked as it should. So maybe try that loader first.
